I'm happy to announce some enhancements to the Description of a Project (DOAP) vocabulary.

DOAP is an RDF schema for describing software projects, and has found widespread use in recent years, including in the GNOME and Apache projects.

This release incorporates the following changes.

At RailsConf 2009, I'll be presenting a three hour tutorial on the configuration management system, Chef — Running the Show: Configuration Management with Chef.

Configuration management isn't just for sysadmins any more. Even one-person projects often need to scale over several servers, whether physical, or in the cloud. Configuration management plays a key part in making that practical.

Chef is configuration management for the internet age. Under the hood you'll find Ruby, Git, HTTP, OpenID, JSON and more. As developers become increasingly responsible for operations, Chef helps you manage your servers by writing code, not running commands.

Come along to find out more, and register for RailsConf 2009 now!

Last week's Web 2.0 Expo was an important milestone in the life of Expectnation, the conference management software I created.

We checked in around 8,300 attendees — see Jen Pahlka's write-up — with no queues and little waiting for anybody. At its peak, this was about one person every ten seconds.

Additionally, Web 2.0 Expo used Expectnation's new attendee networking features, and we've seen a great stream of comments and interaction on the site. I'm looking forward to building on these features to further improve the conference experience.

A happy thing.

Well, in theory you could write a program to generate maps.txt from some kind of availability information.

Thanks Dan. The attendee networking is "just enough" social network to make the conference work harder for attendees who want to meet each other, tell other attendees about themselves, and use direct messaging. The relationships persist over all Web Expo/O'Reilly events.Future enhancements will likely include linking to FB and other social networks. We don't want to be a social network in our own right, as much as to help the normal process of networking at a conference.

I think that is an artifact of my i-photography. The color scheme worked out pretty great as a whole, but you're right about how the photo looks.
